Daim Ntawv Thov Praseodymium oxide
1: Praseodymium Oxide, tseem hu ua Praseodymia, siv los pleev xim rau cov iav thiab cov enamels; thaum sib xyaw nrog lwm cov ntaub ntawv, Praseodymium tsim cov xim daj huv si hauv iav.
2: Cheebtsam ntawm didymium iav uas yog xim rau welder lub tsom iav, kuj yog cov khoom ntxiv tseem ceeb ntawm Praseodymium daj pigments.
3: Praseodymium Oxide nyob rau hauv cov tshuaj khov kho nrog ceria, lossis nrog ceria-zirconia, tau siv los ua cov catalysts oxidation. 4: Nws tuaj yeem siv los tsim cov hlau nplaum muaj zog siab uas paub txog lawv lub zog thiab kev ua haujlwm ntev.
